The old function tried to work in elements which isn't, strictly speaking,
a valid thing to do. In the case of a non-power-of-two format, there is no
guarantee that the x offset into the tile is a multiple of the format
block size. This commit refactors it to work entirely in terms of a tiling
(not a surface) and bytes/rows.

With the new blit framework we aren't using array textures and, from
talking with Nanley, we don't think it's going to be useful in the future
either. Just get rid of it for now.

This function differs from the open-coded implementation in that the
ImageView's width is determined by the caller and is not unconditionally
set to match the number of texels within the surface's pitch.

Since we're using texelFetch with a sampled image, a sampler is no
longer needed. This agrees with the Vulkan Spec section 13.2.4
Descriptor Set Updates:
sampler is a sampler handle, and is used in descriptor updates for types
VK_DESCRIPTOR_TYPE_SAMPLER and VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER
if the binding being updated does not use immutable samplers.

The texelFetch operation requires that the sampled texture coordinates
be unnormalized integers. This will simplify the copy shader for
w-tiled images (stencil buffers).
v2 (Jason):
Use f2i for texel coords
Fix num_components indirectly
Use float inputs for interpolation
Nest tex_pos functions

Also, change the formatting to contain most lines
